GATE FOR RAILROAD-CROSSINGS.

ESEECIFICATIQN forming part of Letters Patent No. 351,325, dated Gotober 19, 1886.

Application filed Ju y 25, 1885.

T0 at whom it may concern:

Be it known that I, Tnoams H. KNoLLIN, of Syracuse, in the county ofOnoudaga, in the State of New York, have invented new and useful Improvements in Gates for Railroad Crossings, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to the class of gates which are designed for the crossings of railways.

The invention consists, essentially, of a gate comprising a barrier extended across the roadway and suspended at its ends by cables or chains running over pulleys pivoted to elevated supports, and thence to one and the same side of the road, to be operated thereat conjoiiitly, all as hereinaftermore fully described, and specificallyset forthin the claims.

In the accompanying drawings, Figure I is a front elevation of a gate embodying my improvements. Fig. II is a side view of the same, and Fig. III a detail View of the arrangement of the pulleys pivoted to the upper end of one of the standards for guiding the cables or chains from one side of the track across to the opposite side thereof.

Similar letters of reference indicate corre sponding parts.

A A represent a set of standards arranged, respectively, at opposite sides of the roadway, two of such sets of standards being placed at opposite sides of the railway, as represented in Fig. II of the drawings. These standards I prefer to construct of two metal tubes placed inclining toward each other at their upper ends and clamped together by stout crossplates, and a third metal tube secured to the upper end of the other aforesaid two-tubes and projecting upward therefrom, as illustrated in Fig. I of the drawings, said standards be ing clamped onto a sill, F, secured to a proper foundation.

a a designate guide-rods attached longitudinally to the standards A A, and placed with their lower ends inclining from the road, so that two guide-rods diverge from each other toward their lower ends.

B represents a barrier or gate proper. Said barrier is composed either of a cable, chain, or rod, as may be desired,and is movably con- Serial No. 172,602.

nected with the guides a a. by slides 11, provided with rollers Z), by which they run up and down on said guides.

it 10 represent weights attached to the slides: Z) I) or to the ends of the barrier 13, to auto matically draw down the gate or barrier B.

d d are cables or chains extended from the slides b b over pulleys c c, pivoted to the up per ends of the standards A A, and thence to one and the same side of the road. The cable or chain (1 runs from the pulley c of one standard directly across to the pulley c of the opposite standard, and thence the two cables or chains (Z (1 run to a winch, O, pivoted to the foot of the standard A, to which winch the cables are attached so as to be wound conjointly thereon. In winding upthe two cables aforesaid they are caused to draw up the barrier B and raise it to a proper elevation clear of the roadway, as represented by dotted lines in Fig. I of the drawings. WVhen it is desired to close the gate,the cables or chains d d are to be unwound from the winch O, and

when this is done the weights to w draw the barrier B down to the position represented by full lines in Fig. I of the drawings. In the descent of the barrier B, together with the slides 12 b, the divergent guides a a increase the tension of the flexible barrier, so as to bring it to nearly or quite a horizontal position. The intermediate portion of the barrier is supported by suspenders e e, which connect said portion of the barrier to that portion of the cable or chain it which runs from the top of one standard across the road and to the top of the other standard, as illustrated in Fig. I of the drawings. The construction of the gate at the opposite side of the railway is a duplication of that hereinbefore described, with the-exception of the winch O. The cables or chains (2 of this second gate are extended from the pulley c on the upper end of the standard A, around a pulley, f, pivoted on the standard above the pulley c, and are thence extended across the railway to a pulley, f, pivoted to the upper end of the standard A thereat and thence to the winch C, so that both gates are operated simultaneously by the turning of the winch.

In order to enable the standards A A to resist the strain incident to the draft on the constructed of single upright pieces or standcables or chains d, I connect the two standards at opposite sides of the railway by a brace or beam, D, extended across the railway and secured to the upper ends of the standards, as represented in Fig. II of the drawings.

I am aware that railway-gates have been ards having ribs cast or made integral therewith, said ribs serving as guides for sliding weights, to which is attached a barrier, the

, weights being raised and lowered by means of chains running over pulleys, and such construction I do not claim, broadly; but

'What I claim as new, and desire to secure by Letters Patent, is-

1. A gate comprising two standards at 0pposite sides of the road, guides secured longi tudinally on said standards and disposed with their lower ends inclining from the road, and

a flexible barrier extended across the road and movably connected with the said guides, substantially as set forth.

intermediate portion of the barrier B, substantially as described and shown.

In testimony whereof I have hereunto signed my name and affixed my seal, in the presence of two attesting witnesses, at Syracuse, in the county of Onondaga, in the State of New York, this 22d day of July, 1885,

THOMAS H. KNOLLIN. [L. s.]
